Grieving family members are seeking justice after a father-of-three had his throat cut shortly after arriving on the Caribbean island of Jamaica for a business trip.

Keith Murrain, 54, who lived in Edgbaston, Birmingham, was found dead in a shallow grave in a field near Spanish Town – dubbed Jamaica's murder capital – after he was snatched from his car at gunpoint.

"We, as a family, want justice. Why kill him? Why not just rob him? I want the people who did this to hang, " his sister, Jenifer, told the Birmingham Mail.

Murrain was abducted and bundled into a waiting vehicle as he left Kingston's Norman Manley Airport.

He was a regular visitor to Jamaica, where he reportedly had a home in the gated Caribbean Estates Community, said to boast "Fort Knox-esque security". His business exported engineering parts to the country and Trinidad.

Fighting back tears, his brother, Samuel, 35, said: "My brother is the latest in a line of businessmen to be murdered. It has to stop.

"He went to sort out his business affairs and he was kidnapped and had his throat cut."

A Foreign Office spokesman said: "We are aware of the death of a British national in Jamaica and are providing consular assistance to the family at this difficult time."

In 2011, the island, with a population of 2.7million, endured 1,124 murders, 1,322 shootings, 738 rapes and 3,033 robberies, the US Bureau of Diplomatic Security revealed.
